See ur ABS ECU(Electronic Control Unit) enables ur brake pads to hold and relief the brake disc... and so as it is kept close to the engine it gets heated up.

Abs actuator toyota


Remove the front wheels and inspect the ABS connector wires that run above the control arm. Chances are you will find that these wires are damaged.The ABS is in or around the wheel bearing and there is a clip that can be gently pried back to remove the ABS plug from the Wheel bearing sensor or the external sensor in that area.
Sometimes a faulty alternator will light up the ABS sensor light. Check to see if the vehicle is charging when this light is on., typical voltages while the car is on should be around 12.5 to 14 volts. You can test it right at the battery while the car is running.
Sometimes an alternator will only go faulty once the component inside get hot.
Typically the wires to the Wheel Hub sensor goes bad from exposure to the elements, especially snow and ice climates or rocks and dirt-roads a lot or if you go through bushes a lot.

I recently replaced the engine on my Citroen c4 2005 model, now the warning lights stay on, the engine overheat, abs and anti pollution warning lights stay on.


The problem for engine overheating rise due to insufficient refrigerant. Try recharging the refrigerant tank with fresh refrigerant and water. If the refrigerant in the tank is of poor quality then also engine overheat.

The reason for ABS light to come may be due to air in the brake fluid line. Try brake bleeding to remove the air bubbles. Also the faulty brake actuator line may cause the problem. Check for actuators on each wheel.

Pollution warning light comes on if the exhaust system not works properly. Check for faulty Oxygen sensor or faulty catalytic convertor.

Abs light stays on I have put new brake line on new calipers because they were sticking causing brakes to get hot, thats all fixed but light still stays on.


the ABS light is on because there has been a fault detected by the ABS module. It has nothing to do with the actual braking system.

The ABS module does a self check every time you start the vehicle. If it detects a problem during that self check the ABS light will stay illuminated and a code or codes for the fault will be stored in the ABS module. Scanning the module will allow you to pull the codes and proceed with diagnosing why the fault is occurring.

The most common source of ABS problems is bad wheel speed sensors or broken wires to the wheel speed sensors. Again pulling the codes from the ABS module will narrow down the possibilities.

Once you now what codes are present post them and we will be happy to assist you further.

2005 toyota prius abs brake not working warning light and abs lights all stay on toyota cant fine problem they say the brakes are fine they want to put in a main chip which well cost $2500 i beg to differ...


Hmm, I'm not sure what a main chip is but, there is a few reasons for this problem.
  1. ABS Sensors - there could be something wrong with a sensor and/or the wiring to them
  2. The wheel bearing speed sensor in a wheel is bad or intermittent which then tells the computer that wheel is traveling at a faster or slower rate of speed then the rest which in then the computer turns the abs light on.
Now when your warning lights go on, the computer sets a DTC code which is the key to helping solve this problem. If you can get the DTC (Data Trouble Code) from the dealership or from someone who can scan your can, I can better assist you in figuring out what's wrong. Hope this helps.

My DSC and Brake warning lamps continuously light up in yellow once the engine has warmed up. They remain on after driving for a while and sometimes they shut off. Any ideas?


Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car

When I restart the engine when hot, the ABS and Brake lights come on and stay on. Not when a cold start


It sounds like the ABS accumulator needs to be replaced. If you crack the line open at the ABS module and the fluid comes out with lots of pressure then you have confirmed this suspicion.

My brakes pedel trembles


For some reason the abs is applying itself prematurely. This could be happening for several reason
1. bad abs sensors (4) one in each wheel
2. bad axle (if axle was replace make sure that its a abs axle).
3.Bad abs Unit or abs computer.
Have the vehicle put on scanner and check for fault code. Auto-Zone does this check for free then you can take it from there.

Enhanced Traction System Warning Light (TRAC OFF)


Sometimes it's a complaint with the ABS braking system. If it comes on and you have no other problems and stays on for while, check your brakes. I have had this issue before and had my brakes replaced. They were worn but for some reason were not squeaking.
